How working memory works: What you need to know

A New Yorker cartoon has a man telling his glum wife, “Of course I care about how you imagined I thought you perceived I wanted you to feel.” There are a number of reasons you might find that funny, but the point here is that it is very difficult to follow all the layers. This is a sentence in which mental attributions are made to the 6th level, and this is just about impossible for us to follow without writing it down and/or breaking it down into chunks.

Maybe it has nothing to do with self-control

I recently reported about a finding that refines a widely-reported association between self-regulation and academic achievement. This association relates to the famous ‘marshmallow test’, in which young children were left alone with a marshmallow, having been told that if they could hold off eating it until the researcher returns, they would get two marshmallows.

Why asking the right questions is so important, and how to do it

Research; study; learning; solving problems; making decisions — all these, to be done effectively and efficiently, depend on asking the right questions. Much of the time, however, people let others frame the questions, not realizing how much this shapes how they think.

Using strategies effectively

  • You can predict how well a student will do from their use of study strategies. Forget intelligence. Forget hours put in. What’s important is the effective use of good study strategies.

To use a strategy effectively, you need to understand why it works, how it works, when it works and when it doesn’t.

For example, all students take notes — not everyone knows how to do it well. Research into the effectiveness of note-taking has found — surprise, surprise — that sometimes note-taking helps you remember information, and sometimes it doesn’t1.

Effective note-taking is more complex than simply knowing some strategies. Every learning situation is different. Every piece of text is different. Every lecture is different. It’s not enough to have a stock way of organizing your notes, and to try and push all the information that comes your way into that format. Sometimes a matrix structure might be best; sometimes a multimedia summary, sometimes a map, sometimes standard old linear notes. It depends on the information and it depends on how it is packaged.

The only way to know which strategy to use when, is to understand how they work.

For example, the primary value of note-taking is to select out the important information and connect it to other pieces of information. If you think the function of note-taking is simply to record what someone has said, or what you've read, then your note-taking will be far less effective.

Successful remembering requires effective self-monitoring

We forget someone’s name, and our response might be: “Oh I’ve always been terrible at remembering names!” Or: “I’m getting old; I really can’t remember things anymore.” Or: nothing — we shrug it off without thought. What our response might be depends on our age and our personality, but that response has nothing to do with the reason we forgot.

We forget things for a number of short-term reasons: we’re tired; we’re distracted by other thoughts; we’re feeling emotional. But underneath all that, at all ages and in all situations, there is one fundamental reason why we fail to remember something: we didn’t encode it well enough at the time we learned/experienced it. And, yes, that is a strategy failure, and possibly also a reflection of those same factors (tired, distracted, emotional), but again, at bottom there is one fundamental reason: we didn’t realize what we needed to do to ensure we would remember it. This is a failure of self-monitoring, and self-monitoring is a crucial, and under-appreciated, strategy.

I’ve written about self-monitoring as a study skill, but self-monitoring is a far broader strategy than that. It applies to children and to seniors; it applies to remembering names and intentions and facts and experiences and skills. And it has a lot to do with cognitive fluency.

Cognitive fluency is as simple a concept as it sounds: it’s about how easy it is to think about something. We use this ease as a measure of familiarity — if it’s easy, we assume we’ve met it before. The easier it is, the more familiar we assume it is. Things that are familiar are (rule of thumb) assumed to be safe, seen as more attractive, make us feel more confident.

And are assumed to be known — that is, we don’t need to put any effort into encoding this information, because clearly we already know it.

Familiarity is a heuristic (rule of thumb) for several attributes. Fluency is a heuristic for familiarity.

Heuristics are vital — without these, we literally couldn’t function. The world is far too complex a place for us to deal with it without a whole heap of these rules of thumb. But the problem with them is that they are not rules, they are rules of thumb — guidelines, indicators. Meaning that a lot of the time, they’re wrong.

That’s why it’s not enough to unthinkingly rely on fluency as a guide to whether or not you need to make a deliberate effort to encode/learn something.

The secret to getting around the weaknesses of fluency is effective testing.

Notice I said effective.

If you intend to buy some bread on the way home from work, does the fact that you reminded yourself when you got to work constitute an effective test? Not in itself. If you are introduced to someone and you remember their name long enough to use it when you say goodbye, does this constitute an effective test? Again, not in itself. If you’re learning the periodic table and at the end of your study session are able to reel off all the elements in the right order, can you say you have learned this, and move on to something else? Not yet.

Effective testing has three elements: time, context, and feedback.

The feedback component should be self-evident, but apparently is not. It’s no good being tested or testing yourself, if your answer is wrong and you don’t know it! Of course, it’s not always possible to get feedback — and we don’t need feedback if we really are right. But how do we know if we’re right? Again, we use fluency to tell us. If the answer comes easily, we assume it’s correct. Most of the time it will be — but not always. So if you do have some means of checking your answer, you should take it.

[A brief aside to teachers and parents of school-aged students: Here in New Zealand we have a national qualifying exam (actually a series of exams) for our older secondary school students. The NCEA is quite innovative in many ways (you can read about it here if you’re curious), and since its introduction a few years ago there has been a great deal of controversy about it. As a parent of students who have gone through and are going through this process, I have had many criticisms about it myself. However, there are a number of good things about it, and one of these (which has nothing to do with the nature of the exams) is a process which I believe is extremely rare in the world (for a national exam): every exam paper is returned to the student. This is quite a logistical nightmare of course, when you consider each subject has several different papers (as an example, my younger son, sitting Level 2 this year, did 18 papers) and every paper has a different marker. But I believe the feedback really is worth it. Every test, whatever its ostensible purpose, should also be a learning experience. And to be a good learning experience, the student needs feedback.]

But time and context are the important, and under-appreciated, elements. A major reason why people fail to realize they haven’t properly encoded/learned something, is that they retrieve it easily soon after encoding, as in my examples above. But at this point, the information is still floating around in an accessible state. It hasn’t been consolidated; it hasn’t been properly filed in long-term memory. Retrieval this soon after encoding tells you (almost) nothing (obviously, if you did fail to retrieve it at this point, that would tell you something!).

So effective testing requires a certain amount of time to pass. And as I discussed when I talked about retrieval practice, it really requires quite a lot of time to pass before you can draw a line under it and say, ok, this is now done.

The third element is the least obvious. Context.

Why do we recognize the librarian when we see her at the library, but don’t recognize her at the supermarket? She’s out of context. Why does remembering we need to buy bread on the way home no good if we remember it when we arrive at work? Because successful intention remembering is all about remembering at the right time and in the right place.

Effective encoding means that we will be able to remember when we need the information. In some cases (like intention memory), that means tying the information to a particular context — so effective testing involves trying to retrieve the information in response to the right contextual cue.

In most cases, it means testing across a variety of contexts, to ensure you have multiple access points to the information.

Successful remembering requires effective monitoring at the time of encoding (when you encounter the information). Effective monitoring requires you not to be fooled by easy fluency, but to test yourself effectively, across time and context. These principles apply to all memory situations and across all ages.

 

Additional resources:

If you want to know more about cognitive fluency and its effect on the mind (rather than memory specifically), there's nice article in the Boston Globe. As an addendum (I'd read the more general and in-depth article in the Globe first), Miller-McCune have a brief article on one particular aspect of cognitive fluency -- the effect of names.

Miller-McCune have have a good article on the value of testing and the motivating benefits of failure.

Regulating your study time and effort

  • Knowing how well or how poorly you know something is critical to effectively allocating your study time and effort.
  • The more difficult the material being learned, the worse we tend to be at estimating how well we know it.
  • Various learning strategies improve our awareness of how well we know something.
  • Learner attributes are also important, particularly our attitudes to learning and beliefs about our abilities.

In general, the weight of the research evidence suggests that college students tend to have a poor sense of how prepared they are for testing, and having been tested, they have a poor sense of how well they did! (This, of course, is even more true of younger students).

Does it matter?

Well, yes, it does. Being able to accurately estimate how well you've learnt something (monitoring) allows you to better allocate your time and energy (self-regulation). You don't want to spend more time than you need on particular topics; you also don't want to short-change topics that need more work.

We tend to be better at regulating our time and effort when the material to be learned is simple.

Obviously, also, some people are much better than others at knowing how well they know something. What distinguishes those people who have a good metacognitive sense and those who don't?

Well, partly, it's about the strategies used in learning. Taking notes, for example, tends to make you more aware of what you know and what you don't know.But not only note-taking; any strategy that causes you to process the material more thoroughly should have this result.

Studies have found that your monitoring accuracy can be improved:

  • when you monitor your learning after a short delay, rather than immediately after studying the material [1]
  • when items are actively generated and not simply passively read [2]
  • by having practice tests of the material [3]
  • by summarizing the material [4]
  • by generating keywords -- but only if, again, you delay a little while before generating them [5]

In general, it seems that students tend to be better at predicting their ability to recall information than their understanding -- as evidenced by their ability to apply the information and make inferences about it. It is of course easier to test your memory than your understanding, and it may well be that students tend not to clearly distinguish between these two aspects of learning. However, certain strategies, such as taking notes (although it depends on the nature of the notes!), do lend themselves to helping develop understanding more than memory.

One final thing is worth noting. It's not only about strategies. Monitoring accuracy is also affected by learner attributes — which doesn't mean you can excuse yourself on the grounds you're "not smart enough"! Studies have found that IQ rarely is a significant factor once background knowledge and other factors (such as socioeconomic status) are accounted for [6]. What looks like being of importance is the student's chronic dispositional status toward learning -- that is, their general attitude to it. For example, those who believe intelligence is malleable and can be increased are more likely to work on increasing their skills, compared to those who believe intelligence is fixed, who tend to focus more on demonstrating good performance, often by choosing only those sort of tasks at which they can do well [7].

Metacognitive questioning and the use of worked examples

The use of worked examples

We're all familiar, I'm sure, with the use of worked-out examples in mathematics teaching. Worked-out examples are often used to demonstrate problem-solving processes. They generally specify the steps needed to solve a problem in some detail. After working through such examples, students are usually given the same kind of problems to work through on their own. The strategy is generally helpful in teaching students to solve problems that are the same as the examples.

Worked-out examples are also used in small-group settings, either by working on the example together, or by studying the example individually and then getting together to enable those who understood to explain to those who didn't. Explaining something to another person is well-established as an effective method of improving understanding (for the person doing the explaining -- and presumably the person receiving the explanation gets something out of it also!).

Metacognitive differences between high and low achievers

An interesting study comparing the behavior of high and low achieving students who studied worked-out examples cooperatively found important differences.

High achievers:

  • explained things to themselves as they worked through the examples
  • tried to construct relationships between the new process and what they already knew
  • tended to infer additional information that wasn't directly given

Low achievers on the other hand:

  • followed the examples step-by-step without relating it to anything they already knew
  • didn't try to construct any broader understanding of the procedure that would enable them to generalize it to new situations

Other studies have since demonstrated that students taught to ask questions that focus on relating new learning to old show greater understanding than students taught to ask different questions, and both do better than students who ask no questions at all.

Learning to ask the right questions

An instructional method for teaching mathematics that involves training students to ask metacognitive questions has been found to produce significant improvement in students' learning. The method is called IMPROVE -- an acronym for the teaching steps involved:

  • Introduce new concepts
  • Metacognitive questioning
  • Practise
  • Review
  • Obtain mastery on lower and higher cognitive processes
  • Verify
  • Enrich

There are four kinds of metacognitive questions the students are taught to ask:

  1. Comprehension questions (e.g., What is this problem all about?)
  2. Connection questions (e.g., How is this problem different from/ similar to problems that have already been solved?)
  3. Strategy questions (e.g., What strategies are appropriate for solving this problem and why?)
  4. Reflection questions (e.g., does this make sense? why am I stuck?)

A study that compared the effects of using worked-out examples or metacognitive questioning (both in a cooperative setting) found that students given metacognitive training performed significantly better than those who experienced worked-out examples (the participants were 8th grade Israeli students). Lower achievers benefited more from the metacognitive training (not surprising, because presumably the high achievers already used this strategy in the context of the worked-out examples).
